how to chek for the number of options in an app

[Sean McMahon]

commands usually start with - or -- so you could type command --help, where
command is the name of the command you are looking for, pipe that through grep
for the string '-' or '--' then pipe that through wc.  That might give you some
idea I'd look at the help or man pages first to see the syntax of how they show
you options so you can see how to grep for a sensible search string.  This
sounds like some kind of tricky way to answer some random exam question?

Hi all,
Is there a way to check, without counting by hand within the manual, how many
options are there for a command such as ls, more, bash, etc?
If not, what's the shortest way of doing that through the man?

Many thanks in advance!
Ned
